Hi, I am also hitting this bug when enabling cache driver  
"eaccelerator" in horde/conf.php

Including the print statement suggested didn't help:

horde/imp/lib/IMAP/Cache.php

  function getCache($imap, $mailbox, $key = null, $check = true)
     {
         $imp_imap = &IMP_IMAP::singleton();
         $res = parent::getCache($imp_imap->stream(), $mailbox, $key, $check);
         if ($this->_usecache &&
             ($res === false) &&
             !isset($this->_cache[$mailbox])) {
             require_once 'Horde/Cache.php';
             $cache =  
&Horde_Cache::singleton($GLOBALS['conf']['cache']['driver'],  
Horde::getDriverConfig('cache', $GLOBALS['conf']['cache']['driver']));
             $res = $cache->get($this->_getHordeCacheID($mailbox),  
$GLOBALS['conf']['mlistcache']['lifetime']);
             if ($res === false) {
                 $this->_cache[$mailbox] = array('d' => array(), 'k' => null);
             } else {
                 require_once 'Horde/Serialize.php';
                 print_r($res);
                 $this->_cache[$mailbox] =  
Horde_Serialize::unserialize($res, SERIALIZE_BASIC);
                 $res = parent::getCache($imp_imap->stream(),  
$mailbox, $key, $check);
                 Horde::logMessage('Retrieved ' . $mailbox . ' from  
cache.', __FILE__, __LINE__, PEAR_LOG_DEBUG);
             }
         }
         return $res;
     }
